[Cameramakers] Jouney to the Dark Slide.
I found this material in http://www.mcmaster.com/catalog that looks like it may possibly be the material that is used in commercial film holdersfor dark slides. It is called garolite grade xx ( type that into its search engine). It is a paper based phenolic laminate, available in opaque black It is available from extremely thin to very thick (1/32 , 1/16, 1/8, up to to 1 1/2 inches ). It is a solid paper material impregnated with a synthetic resin formed under pressure and heat..It has high dielectric and impact strength and tensile strength and is resistant to heat, moisture, chemicals , oil , corrosive solutions and just about everything else It is also very light weight, , dimensionally stable and easy to machineplastic resin material that is mixed with paper and forms a very rigid high impact material available in opaque black it is also very light...And is very cheap. A 36" x 24 inch sheet in 1/16 inch is $10.00!. There are other more expensive versions of this material that are different colors and use cotton or fiberglass with the resin It is used for circuit boards ect... Does anyone have any experience in using this material for dark slides John Cremati...
Re: [Cameramakers] Jouney to the Dark Slide.
Really, that sounds like a REALLY useful material. Did you catch the tensile strength? That's in the aircraft grade aluminum neighborhood! I can think of a lot of uses for that stuff. I think I'll be ordering some. Probably make great lensboards too.

[Cameramakers] basics of using view camera as enlarger
Hello: If this is an appropriate venue to discuss this topic, I'd like to hear from people who have used their view cameras to make an enlarger - whether a minimalist approach (mine) or not. Just looking for some basics or reading material so I don't have to 'reinvent the wheel'...someone else's experience on how much room is needed, how rigid the structure needs to be, etc. I'm interested in building 8 x 10 (or so) camera/enlarger. Probably use a homebrewed cold head, have a 15 process lens coming, and have a too-big (18 x 24) bellows...might look for something smaller. I gather (dumb question - I haven't built or used a view camera yet - so I have no practical understanding other than what I read) a bellows really IS necessary...can't just move the enlarger head up down because the negative-lens distance relates to the lens to paper distance. A box camera fixed at infinity is do-able, but for an enlargerh, I guess that would severely restrict the flexibility if it would be very useful at all.
